Require test scripts for CW codes in LALApps

As highlighted by CW/software/lalsuite#62, some important CW codes in LALApps do not have a test suite, which can allow bugs to creep in. This issue is to coordinate an effort to either provide a test suite for every CW code in LALApps, or else remove from LALApps any CW codes for which a test suite cannot be provided (due to e.g. the code being deprecated, no longer maintained, etc.)

Each code which has a test suite should be checked off the list below:
